I split the sent patchset, please consider this part for current. I'll send a test for [1] in a day or so. Regarding [3], Jens, I haven't looked properly yet, how long splice can wait on a inode mutex, but it can be problematic, especially for latencies. How about go safe for-5.7, and maybe think something out for next?
